cubic yard. A cubic yard may be considered equal to 1^ ton. In 
many places along the line of railway the marl series is so situated 
Avith respect to it, risine: rapidly 40 feet and more above its level, 
that it can be worked (if worked on a large scale) at a cost not 
exceeding fourpence per cubic yard, for raising and filling into 
railway trucks. I suppose the marl let to a contractor, paying- 
threepence per yard royalty, and making a profit to the same 
amount on the working of it. The following would then be the 
cost of dressing an acre of land with marl, carried 30 miles 
on the railway, and applied at the rate of 20 cubic yards to the 
acre : —

The first sum, however, of 3/. 5^,, would only be the cost of 
marling close to the railway. At a distance of five miles 
from it we must add 3/. 15^. for cartage, bringing the total 
cost up to 11. At that cost the marls of the New Forest would 
be accessible to a tract of country, including the Forest itself, 
should it ever be brought under cultivation, containing 300 
square miles, or 192,000 acres, on the west, to say nothing of 
lands which might derive benefit from them for an equal 
distance on the east. An acre of marl, ten yards deep, would 
produce 605/., or 60Z. IO5. for every yard of depth, at a royalty 
of three-pence the yard, and would dress 2420 acres, at the rate 
of 20 cubic yards to the acre. Eighty acres would more than
